As oil and gas projects become larger and more complex, AI is enabling companies to rethink traditional approaches to planning, engineering and execution. Based on an in-depth conversation between Arun Bhardwaj, Editorial Director of EM Magazine, and Vijay Garg, Oil and Gas Tech Solution Expert, this article examines the FEL-to-EPC journey and how AI is driving faster, smarter and more efficient project delivery.
The O&G industry operates at a scale where a single new refinery or petrochemical complex can require investments running into thousands of crores, take five to seven years from initial concept to first production, and involve hundreds of engineering disciplines, equipment vendors, contractors, and regulatory approvals working in precise sequence. This column explains how Oil and Gas capital projects are planned, built, and enhanced and optimised through advanced artificial intelligence.
Roadmap for Capital Project
Navigating this volatile market successfully requires a vital framework that transforms strategic energy blueprints into reality.
Every major O&G capital project, including a new refinery, a gas processing unit, a petrochemical complex, or a capacity expansion, moves through two broad phases. The first is planning, governed by a rigorous framework known as the Front-End Loading (FEL) process. The second is execution, carried out by Engineering, Procurement and Construction (EPC) companies. Understanding how these two phases work and how technology is reshaping the process is essential for every company that operates within, or depends upon, this industry.
Capital Project Planning: The FEL Process
Front-End Loading (FEL) is the structured, stage-gated planning framework used by O&G companies to define, evaluate, and approve capital projects before committing to full execution. In the O&G industry, when a company plans to establish a new plant or expand the capacity of the existing facility, it is required to answer critical questions before contractor engagement and steel procurement, such as: Why is capacity expansion needed? What is the demand signal, and how is it driven? Where can the output be sold, and what markets exist for it? What feedstock is available, at what cost and its sources? These questions define the business, forming the foundation of the FEL process.
- FEL 1: Feasibility and Market Study
FEL 1 is the feasibility phase that involves a high-level assessment of whether the project is technically and commercially viable. At this stage, the oil and gas company conducts a market survey to understand demand, pricing dynamics, competitive landscape, and available feedstock. If the company is evaluating a capacity expansion, it will study what the incremental demand is, which geographies it can serve, what the input feedstock analysis reveals about supply security and cost, and where in the value chain the opportunity sits.
- FEL 2: Scenario Simulation and Concept Selection
If FEL 1 is approved, the project advances to FEL 2 where, to evaluate different approaches to the project, the team develops two or three viable scenarios, runs detailed financial simulations for each that include covering capital cost estimates, operating cost projections, return on investment, and budget requirements, and then selects the one that best balances technical performance with financial viability. The selected concept then becomes the basis for the project plan that will be carried forward into execution. Getting the scenario selection right at FEL 2 is critical, as changing fundamental design decisions later in the project becomes exponentially more expensive
The entire FEL process from initial feasibility through concept selection to final project definition is conducted entirely by the oil and gas company itself, using its own engineering teams, technical specialists, and financial analysts. All the machinery specifications, process designs, layout requirements, and project definitions are determined before the project is handed over for construction.
The EPC Phase: Execution and Project Delivery
Once the FEL process is complete and the project has received full funds authorisation, the oil and gas company transitions from planning to execution. This is where the EPC, that is Engineering, Procurement and Construction companies, are engaged. These companies are specialist contractors who are expected to take an approved, fully defined project design and physically build it on time, on budget, and to specification.
The scope of an EPC contract is vast. On the Engineering side, the EPC company translates the project’s conceptual and basic designs into detailed engineering drawings, specifications, and construction packages. On the Procurement side, it sources and manages the supply of all equipment, materials, and components, from reactors and compressors to valves and instrumentation. On the Construction side, it manages civil works, erection, installation, and commissioning, bringing thousands of workers, subcontractors, and specialist teams together on site.
The Oil and Gas EPC Market Outlook
Driven by rising energy consumption and infrastructure upgrades, the market for EPC companies is undergoing a massive digital and structural shift both globally and within India. The oil and gas EPC market is currently valued at roughly $60.66 billion to $65.96 billion and is projected to grow to over $102 billion by 2034 at a steady CAGR of 5.6%.
In India, Larsen and Toubro’s Hydrocarbon Engineering division (L&T Energy Hydrocarbon) is one of the largest and most active EPC contractors in the oil and gas sector. In December 2025, L&T Energy Hydrocarbon secured the largest EPC contract of two major cross-country gas pipelines from a prestigious Middle East client. Engineers India Limited (EIL), another major PSU EPC and project management consultancy, was entrusted by HPCL with the Vizag Refinery Modernisation Project, involving a total awarded order value of over Rs 2,500 crore.
AI in Oil and Gas: From Automation to Autonomy
The Oil and Gas Industry is in the early stages of transition, where AI is not only now a distant possibility, but as a present operational reality across the FEL planning process, the EPC execution phase, and broader industry operations. The impact on the FEL process is particularly significant. A planning cycle that currently takes 18 to 24 months is, with AI-assisted engineering tools, being compressed by as much as 50%. EY (Ernst and Young) Digital Operations has documented how AI-driven data optimisation is boosting efficiency and accuracy in oil and gas project management and streamlining engineering processes. Faster FEL translates directly into higher productivity, more efficient use of engineering resources, and reduced operating costs at the planning stage, without sacrificing the rigour that FEL is designed to provide.
Against this backdrop of complex, high-stakes project delivery, artificial intelligence is emerging as a transformative force. For the oil and gas companies that understand the FEL-to-EPC project lifecycle deeply, that embed AI into every stage of planning and execution, and that move from reactive automation to proactive autonomy, will be the ones that define the next era of this industry.
